Parents recently received this letter, it is believed to be a senior prank, to notify that their daughters were undergoing an "inspection".
This is similar to a flyer sent around to Lowell High School students:

Believe it or not, penis inspector Richard L. Dong is not real, and Lowell High School doesn't actually require its seniors to pass a penis inspection before they're allowed to graduate - rather, school officials believe the amusing fliers are just a senior prank orchestrated by members of the school's graduating class.

Joe Pickett and Nick Prueher of the Found Footage Festival posed Prueher as a fictional TV chef named Chef Keith and attempted to get him booked on local morning news shows in the Midwest. The result was five disastrous TV appearances.
